Later on it, when we did "cat /proc/cpuinfo … it shows us only one cpu.From the news group someone suggested us to update the kernel to :kernel-image-2.4.27-2-686-smp Now after updating kernel cat /proc/cpuinfo shows 4 cpus instead of 2 cpus we have. Also it shows only 16 KB cache. I am not sure, it shows L1 or L2 cache.
